Wastegate And Bov Upgrade

[Captain Wow]

I guess it's probably a pretty open ended question, but what's recommended when it comes to wastegate and bov brand and quality wise?

I'm currently running what seems to be a cheap nasty wastegate:

I'm really just after quality at a reasonable price as I don't want to be mucking around with dodgy products. Obviously I'm unsure of what boost pressure will be after a tune but I wouldn't imagine it'd be more than 20psi.

And a TurboSmart bov?:

I'd like to get something reliable on there before I go for a tune in the new year and from what I've heard, that type of bov has been known to leak so I was looking for something like the HKS ssq that has the pull type relief system so as not to allow boost leak. Ideally I'd like something plumb back as tooot toooing isn't my jam lol.

Any help would be appreciated guys,

Cheers,

I have a synchronic 50mm wastegate and plan to get their recirculating valve (bov) as well. They have impressive engineering (pistons instead of diaphragms) but

(a) they are expensive and

(b) tuners don't like them because they are not familiar with them. It took me a while to work out how to set up my w/g.

Tial seems to be the respected brand in waste gates.

I have an HKS sequential bov at the moment that seems to work ok but

(a) its noisy as ...which is why I want to replace it with a plumbed back type and

(b) if you are buying one there are a lot of realistic looking fakes around

Tial or Turbosmart. Buy from a reputable supplier but shop around, as prices vary massively.

Make sure the wastegate comes with enough spring to run your desired boost.

Cheers lads. Tial seems to be readably available over here and not silly money so that might be the go for the wastegate. As for the bov, I might look into GFB recalculating one or a good brand at a decent price.

The Turbosmart Kompact is a great buy for the price, and has worked fine for me for many years now. You may need to swap the springs if it is too tight for your liking, but it is bolt-on.

Any plumb back bov should work fine though. The GTR one has a larger outlet so you may need to muck around with the piping a bit.

I have a stock GTR bov you can have for cheap.
